Circulating MicroRNA Expression, Vitamin D, and Hypercortisolism as Predictors of Osteoporosis in Elderly Postmenopausal Women

Table 2

Correlations between bone markers, cortisol, vitamin D levels, miRNAs, and fracture risk parameters in postmenopausal women with osteoporosis.

Studied parameters	Fracture parameters
	Total BMD (g/cm^2)	score lumbar spine (L2-L4)
OC (ng/ml)	-0.27^a	-0.36^b
CTx (ng/ml)	0.23^a	0.14^b
s-Ca	-0.24^a	-0.26^b
s-BAP	0.38^a	0.42^b
Vitamin-25 (OH)D (nmol/l)	-0.31^a	-0.42^b
Cortisol	-0.18^a	-0.21^b

Data are presented as Pearson’s () coefficients adjusting for variables identified as cofounders in univariate analyses. Significance at . ^a, ^b. BMD: bone mineral density; OC: osteocalcin; CTx: collagen type I c-telopeptide; sBAP: serum bone alkaline phosphatase; s-Ca: serum calcium.
